Your definition of good and evil is only convenient to your own view. A more wider understanding of good and evil will always be decided by a larger majority. If Evil rules the Earth more will side with it, If good rules the Earth then it will have a majority.
The majority won today, evil will hide it's tracks as it cannot face the consequence. The shooter is now probably starting the first day of eternity in hell, after getting use to the pain of soul torture, the Devil may give the tortured spirit some rank, but that day is a long way as the devil loves to masticate his own. That's his way and meaning of love. Imagine not dying in hell over and over again with the pain delivered 24/7.
Make no mistake God said i am Alpha And Omega. I control Satan on Earth.
However God gave us all Free choice, believe or not.
